Description:

TECHNICAL FIELD

[0001] The present invention relates to the field of mobile terminal, and
particularly, to a push-to-talk mobile terminal for dual-use of vehicle
and portability.

BACKGROUND OF THE RELATED ART

[0002] Push To Talk (PTT) or Push to talk over Cellular (POC) mobile
terminals are increasingly used in certain countries or districts.
However, the requirement on battery capacity is higher due to the larger
electrical energy consumption in conversations by interphones, and tone
quality and conversation volume with a louder voice are required due to
noisier voices in certain cars, therefore, a requirement for a Speaker is
higher.

[0003] In addition, if a hand-held PTT mobile terminal is used while
driving, certain security risks will exist. Therefore, current vehicle
PTT mobile terminals are basically fixed in the cars, and only when the
user is inside the car, he/she can use the PTT mobile terminal; however,
when the user is outside the car, he/she uses the additional PTT mobile
terminal, so one user needs to use multiple numbers, but the user is
generally unaccustomed to use multiple numbers. Hence, it is required
that the PTT mobile terminal not only can be used in the car, but also
should be easy to carry and can be used outside the car. However, there
is no such a PTT mobile terminal for the user to choose the use at
presently.

BRIEF DESCRIPTION OF DRAWINGS

[0017] FIG. 1 is a structure diagram of a push-to-talk mobile terminal
according to the present invention.

PREFERRED EMBODIMENTS OF THE PRESENT INVENTION

[0018] The present invention will be further described in combination with
the accompanying drawings and specific embodiments below.

[0019] With regard to a push-to-talk mobile terminal used by a vehicle,
following aspects of requirements exist:

[0020] 1) due to noises, a Speaker with louder volume and better tone
quality is required, for example, an intra-car sound box device is used;

[0021] 2) since more power consumption exists in PTT conversations, it is
required that an interface can implement a charge function;

[0022] 3) in order to enhance safe driving of drivers, it is required that
a key being able to be convenient for use is used as a PTT key (or a key
including the PTT key and possessing other parts of functions) for use.

[0023] In view of the above requirements, the present example provides a
dual-purpose push-to-talk mobile terminal for vehicle and portability. As
shown in FIG. 1, the push-to-talk mobile terminal includes: a mobile
terminal body of push-to-talk, a multifunctional interface socket and
peripheral devices. Wherein, one end of the multifunctional interface
socket is connected with the mobile terminal body, and the other end is
connected with the peripheral devices.

[0024] Furthermore, the peripheral devices comprise: an external Speaker
device, an external PTT keyboard, an external microphone and an external
vehicle power supply. The push-to-talk mobile terminal makes
conversations through the control of the peripheral devices, and when the
mobile terminal body is connected with the multifunctional interface
socket, the push-to-talk mobile terminal controls operations of the PTT
key through the external PTT keyboard of the peripheral devices.

[0025] Furthermore, the mobile terminal body is mainly a mobile terminal
which has a PTT function, and also includes a switch interface, wherein
the switch interface can be designed into a shape of switching by an
elastic sheet. The switch interface can be connected with the
multifunctional interface socket. In the main body design of the mobile
terminal, the size of the mobile terminal is reduced, thus an artistic
exterior of the mobile terminal can be kept.

[0026] In the present example, after the mobile terminal body is connected
with the multifunctional interface socket, the elastic sheet of the
switch interface in elastic sheet shape of the mobile terminal body is
flicked, and the mobile terminal body will automatically lock the PTT key
of the mobile terminal body after detecting such a signal.

[0027] Furthermore, the multifunctional interface socket can be installed
in a car conveniently, which makes a driver can conveniently get hold of
the mobile terminal. The multifunctional interface socket is used to make
the mobile terminal body connect with the peripheral devices, and the
multifunctional interface socket includes: a key switch interface, an
external Speaker interface, a charge interface and an external microphone
interface.

[0028] Furthermore, the multifunctional interface socket also includes a
potential device, an external power supply interface or an external
device interface. Here, the interface between the multifunctional
interface socket and the peripheral device can be designed into a wired
or wireless device.

[0029] It should be illustrated that, when the mobile terminal body is
connected with the multifunctional interface socket, the function of the
PTT key of the mobile terminal body can be automatically disconnected
through the switch interface, and the function of the PTT key is switched
to the external PTT keyboard through the key switch interface of the
multifunctional interface socket. It is mainly because that there is a
long key or a double-click key in use of the PTT key, and there is an
explicit division of labor for pressing the key and releasing the key,
and thus to avoid that the PTT key of the mobile terminal body and the
external PTT key are operated simultaneously.

[0030] In the present example, in order to try to keep clean and tidy and
aesthetic inside the car, the external PTT keyboard can be designed into
a keyboard like a wrist watch and buckled on a place of a steering wheel
on which the driver can touch conveniently.

[0031] It should be pointed that, when the mobile terminal body is
connected with the multifunctional interface socket, a Speaker of the
mobile terminal body can be automatically disconnected through the switch
interface, and conversation voices are broadcasted through the external
Speaker device. Here, the external Speaker device is similar to an
interface of a common headset, and preferably, the external Speaker
device can be in common use with a headset inserting card.

[0032] In the present example, the external Speaker device can be an
intra-car sound box device and is connected with the external Speaker
interface of the multifunctional interface socket. The multifunctional
interface socket can disconnect connections between the intra-car sound
box device and other sound source devices when there is an incoming call,
and broadcasts the conversation voices. For example, when listening to
music in the car, and if receiving the call, the multifunctional
interface socket can automatically disconnect the connection with the
music player, and then turn to broadcast the conversation voices.

[0033] In the present example, the external microphone can be a desktop
microphone and is connected with the external microphone interface of the
multifunctional interface socket. When the mobile terminal body is
connected with the multifunctional interface socket, a built-in
microphone of the mobile terminal body can be disconnected through the
switch interface, and conversations are made through the external
microphone.

[0034] Preferably, the multifunctional interface socket can be placed in a
position close to the front of the driver's seat. One external PTT
keyboard like a wrist watch is installed on the steering wheel, and the
external microphone is placed at the position in front of the driver.

[0035] Furthermore, in order to make the complete set of devices and
vehicle (such as a car, and so on) have independence, the external
Speaker device, the external microphone and the external PTT keyboard can
be an integrated device, and the integrated device is in hand shank
shape, so as to make it convenient for user to use.

[0036] The mobile terminal body can be connected with the multifunctional
interface socket by using a standard voltage adapter, and the charge
interface is connected with the external vehicle power supply to charge
the mobile terminal body.

[0037] The above description is only the specific embodiments of the
present invention, but the protection scope of the present invention is
not limited to the above description. Changes and substitutions, which
can be thought by any person skilled in the art and be within the
technical scope disclosed by the present invention, should be all covered
within the protection scope of the present invention. Therefore, the
protection scope of the present invention should be subject to the
protection scope of the claims.
